Figure 14. Impregnating Machine [Gas mantle manufacture]
- 1915
Figure 14 from the 1915 volume, The Rare Earth Industry depicting a machine (1/10 actual size) for saturating cotton and ramie webs with a solution of rare earth metals during the manufacture of gas mantles. The volume details various industrial applications of rare earths and closely-related elements, including thorium, zirconium, tantalum, and tungsten. Particular attention is given to the illuminating effect of the oxides of thorium and cerium and their application to the manufacture of incandescent gas mantles and electric lamps. The volume also includes chapters on uranium and vanadium, as well as the industry of radioactive substances.
